Water Torpedo Grass regularly, especially during establishment and dry periods. While it can tolerate some drought once established, consistent moisture promotes vigorous growth.

Avoid waterlogged conditions, as this can lead to root rot. Check soil moisture by feeling the top few centimeters; water when dry.

Prune Torpedo Grass to manage its vigorous growth and prevent it from becoming invasive. Cut back overgrown stems to the ground in late winter or early spring before new growth begins.

This encourages denser foliage and can help contain its spread in garden settings.

Torpedo Grass is easily propagated by rhizomes and stolons. Divide established clumps in spring or summer, ensuring each division has roots and shoots.

It can also be propagated from seed, though vegetative propagation is faster and more reliable for maintaining desired characteristics.

Repotting is generally not necessary for Torpedo Grass unless it is grown in a container and has become root-bound. If container-grown, repot into a slightly larger container in spring, using a well-draining potting mix.

For garden beds, its vigorous nature means it will spread rather than need repotting.
